Abstract (en)
[origin: WO2016091544A1] The invention relates to a solenoid valve (26) for controlling a fuel injector (10), comprising a coil (28), an armature-rod assembly (34), and a resilient device (32) provided for moving the armature-rod assembly (34) when the coil (28) is not supplied with power. The resilient device (32) is characterized in that it includes the complementary arrangement of a compression spring (66) having helical coils, and another flexible element (68) that is rigidly connected to the spring (66), wherein said other flexible element (68) is suitable for stopping the propagation of compression and expansion waves in the spring (66).
